Abstract

519,590. Tumbler switches. GENERAL ELECTRIC CO., Ltd., and ASH, A. G. Sept. 26, 1938, No. 27993. [Class 38 (v)] Operation of the dolly 6 of a tumbler switch causes a shoulder 20 on the contact member 17 to move along an inclined surface 13 thereby helping to carry the spring 18 connecting the member 17 to the pivot 15 of the dolly, over the the dead-centre. Tie member 17 is pivoted to the dolly at 16 and carries a roller contact 4 adapted to engage fixed contacts 2 at its ends and so bridge them. The spring 18 is connected to the roller 4 by means of an intermediate insulating member 19.
